Didnt like it. At all.
I hope other people found it hard(er)!
Anyone remember the questions/answers am still in shock - got x=100 y=400 for the linear programming one.
Agreed...I ran seriously short of time....10 mins to do the last 2 questions.....I didnt get that for the liner programming one....but 1 of my friends did....and i didnt get all the inequalities...so it sounds good.
Anyone else run out of time?
i think that those values are right. Or at least that it what everybody else appeared to get (I got y=440 and x =60 cause i couldn't get the inequalities. What were they??)
What did you get for the flow and which of the nodes in the Route Inspection Problem did you say were going to be the starting and ending nodes
Max flow i got to be 64.....but i could only find a min cut of 65.....
Think i had A and D repeating.....
A and D start and finish even.....
yeh, i got a max flow of 64. Was your initial flow 53? Y=16 x=9?
Did you do 2 Flow augmenting paths? First one being of 9 and the second of 1or 2 (can't remember which)????
good, A and D. Cause F and the other one was only 9 in length.
Was the total length 299?
53 initial yeah....
3 augmenting paths.....think they were 8, 1 and 2.....
if the final answer, 64 is the same, it should be fine. Strange, why would we have the difference though?
In the final question, how many workers did you say the project needed to finished on time? I think i said 4.
3....if you devided the total ours by the length of the critical path you got 2.68 or something.....so 3 workers.
But there was were was 3 critical activities that had to take place at the same time. Also, A, had to occur near to the beginning because it only had a float of 2. Thus, also 4 of the activities had to be taking place at the same time. Leading to at least 4 workers being needed.
Anyone else agree or disagree with this?
Btw, what did you get for your value fo the total float? Is it just all the floats added together?
i got max flow 65
initial 53+IDA 9+IFDA 2(back flow)+IFDBE 1(back flow)
anyone agree with it?
did ne1 notice the mistake on the answer booklet for question 1. the matchings, there was 6 dots and they wasnt even numberd. n then da last question why cant you have a complete matching!
i was going to say cz u got bludy 5 vertices on set X and 6 on set y!!
but i said something else.
HEY! somebody who got the same value for the Profit as me, Pounds 196.
But, from what i have heard, we are wrong.
Do you think we could be right. Anyone who got 400 and 100 for x and y, could you please show the inequalities that you got!
Anyone who got 400 and 100 for x and y, could you please show the inequalities that you got!
i got i think:
X ≤ 40/100 (X + Y)
X ≥ 20/100 (X + Y)
Y ≥ 0
and couple more i cant remember
and P = 30/100X + 40/100Y
